Pseudopapilledema of optic disc, left eye

This code describes the presence of an anomalous elevation of the optic disc in the left eye, which clinically mimics true papilledema but is not caused by increased intracranial pressure. It is a benign, congenital anomaly characterized by crowded optic nerve fibers and an absence of true disc edema.

Use this code when documentation confirms pseudopapilledema affecting the left optic disc, typically identified during an ophthalmoscopic examination. This diagnosis is often made after ruling out true papilledema through neuroimaging and lumbar puncture, which would show normal intracranial pressure.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Distinguish carefully from true papilledema (H47.1-) which indicates optic disc swelling due to increased intracranial pressure.
• This code is typically a primary diagnosis when pseudopapilledema is the reason for the encounter, or a secondary diagnosis if evaluated during a routine eye exam.
